WIPO Patent Application WO/2012/091375
Kind Code:
A2
Abstract:
The present invention relates to a container having the function of preventing air backflow within a tube discharge hole. The tube container includes: a tube in which contents are filled, wherein the tube is made of a flexible material; a neck part protruding from the upper end of the tube, wherein the neck part has a discharge hole through which the contents within the tube are discharged; an inner cap sealingly coupled to the upper end of the neck part, wherein the inner cap has a discharge hole through which the contents within the tube are discharged to the outside; and a cap which is screwed onto the outer surface of the neck part so as to prevent foreign substances from being introduced into the tube. The tube container further includes: ribs protruding from the inner surface of the inner cap and spaced a predetermined distance from each other, wherein the ribs have a space therebetween; and a checker which includes an insertion part inserted and fixed to the ribs, and a wing part extending outward from the insertion part such that one end of the wing part contacts the inner bottom surface of the neck part to cover the discharge hole of the neck part, wherein the wing part is folded upward by the discharge pressure so as to open the discharge hole of the neck part. Thus, the container may prevent external air from being introduced into the tube to prevent the contents from being physically deformed or degraded.
